GeneDx RCV003441819 SCV000292981 uncertain significance not provided 2023-11-08 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV001857802 SCV002197486 uncertain significance Intellectual disability, autosomal dominant 6; Developmental and epileptic encephalopathy, 27 2022-11-23 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GRIN2B protein function. ClinVar contains an entry for this variant (Variation ID: 245831). This variant has not been reported in the literature in individuals affected with GRIN2B-related conditions. This variant is present in population databases (rs748005909, gnomAD 0.0008%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1209 of the GRIN2B protein (p.Arg1209Gln).
